fix(train): a day's page of its own, in cards, its night and Recharge drawn in place

The night's chart threw mid-paint where Polar's last phase starts at the
night's end or after it: its right edge was clamped between left + 1 and
the row's width, the lower bound then above the upper (an ArgumentError).
A throw mid-paint leaves the canvas moved, so the rows below and the charts
after them were drawn out of place, the skin temperature's among them. Each
phase now stays within its row, a pixel wide at least.

Nightly Recharge showed Polar's marks for a figure it has none of (-1 for
the recovery and the intervals, -100 for the nervous system's status, 0 for
a baseline not yet learnt) as the person's own. Recharge.known leaves them
out, on the page and in the days' list; the figures are rows, each with the
person's usual below it, and Polar's explanation of them (the status from
-10 to +10, what each measures) is behind halkyon_ui's question mark.

The page is a screen of its own over the tabs, without the bar and with the
way back at its top left, its parts in cards (the developer's review of
3 Nov 2026; D60 had it inside Profile).
